The RTX 2080 Ti has a 318 MHz higher core clock speed and 232 more Texture Mapping Units than the GTX 750 Ti. This results in the RTX 2080 Ti providing 325.9 GTexel/s better texturing performance. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The RTX 2080 Ti has a 318 MHz higher core clock speed and 72 more Render Output Units than the GTX 750 Ti. This results in the RTX 2080 Ti providing 102.3 GPixel/s better pixeling performance. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The RTX 2080 Ti was released over three years more recently than the GTX 750 Ti, and so the RTX 2080 Ti is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GTX 750 Ti when running the latest games.

The RTX 2080 Ti has 9216 MB more video memory than the GTX 750 Ti, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the RTX 2080 Ti also has superior memory performance overall.

The RTX 2080 Ti has 529.6 GB/sec greater memory bandwidth than the GTX 750 Ti, which means that the memory performance of the RTX 2080 Ti is massively better than the GTX 750 Ti.

The GeForce RTX 2080 Ti SLI has 4352 Shader Processing Units and the GeForce GTX 750 Ti Gigabyte OC 2GB Edition has 640. However, the actual shader performance of the RTX 2080 Ti is 7116 and the actual shader performance of the GTX 750 Ti is 959. The RTX 2080 Ti having 6157 better shader performance and an altogether better performance when taking into account other relevant data means that the RTX 2080 Ti delivers a massively smoother and more efficient experience when processing graphical data than the GTX 750 Ti.

The RTX 2080 Ti transistor size technology is 16 nm (nanometers) smaller than the GTX 750 Ti. This means that the RTX 2080 Ti is expected to run slightly cooler and achieve higher clock frequencies than the GTX 750 Ti.

The GeForce RTX 2080 Ti SLI requires 260 Watts to run and the GeForce GTX 750 Ti Gigabyte OC 2GB Edition requires 60 Watts. We would recommend a PSU with at least 650 Watts for the RTX 2080 Ti and a PSU with at least 400 Watts for the GTX 750 Ti. The RTX 2080 Ti requires 200 Watts more than the GTX 750 Ti to run. The difference is significant enough that the RTX 2080 Ti may have an adverse affect on your yearly electricity bills in comparison to the GTX 750 Ti.

Overview
GeForce RTX 2080 Ti is the top RTX 20 Series graphics card and considered an Enthusiast graphics card based on the Turing architecture.
Architecture
The Turing architecture represents a process shrink down to 12nm compared to 14nm Pascal. The Turing architecture provides the world's first consumer support for real-time ray-tracing technology, or RTX.
GPU
It equips a GPU Codenamed TU102 which has 4352 Shader Processing Units, 272 TMUs and 88 ROPs. The central unit runs at 1350MHz and goes up to 1545MHz in Boost mode. It also has 544 Tensor Cores for AI purposes.
Memory
The GPU accesses an 11GB frame buffer of first-gen GDDR6 memory through a 352-bit memory interface, while the Memory clock operates at 1750MHz, or 14GHz effective.
Power Consumption
With a rated board TDP of 285W, it requires at least a 650W PSU with two 8-pin power connectors.
System Suggestions
GeForce RTX 2080 Ti is best suited for resolutions up to and including 3840x2160. We recommend a top-End Processor and at least 16GB of RAM for optimal performance.

GeForce GTX 750 Ti Gigabyte OC 2GB Edition is a special edition of the fast-middle-class GeForce GTX 750 Ti.
This edition comes with a custom cooling cooling solution which by itself will allow a slight performance boost, as GeForce GTX 750 Ti benefits from the GPU Boost 2.0 technology.
Furthermore, it comes overclocked out of the box in the central unit that was raised from 1020MHz to 1033MHz, while the Turbo Boost is now of 1110MHz, instead of 1085MHz. The operating memory clock was left untouched. Further overclocking can be achieved easily, as the GPU has great OC potential.
Benchmarks indicate its performance is only around 1% better than the reference NVIDIA GeForce GTX 750 Ti and thus Radeon HD 7850 and GeForce GTX 650 Ti Boost Edition are still faster.
